Plans are being floated for a 14 turn, 5.1km long race track right at your doorstep, if you stay in London that is. The idea is being proposed and promoted by the banking corporation of Santander, which also happens to sponsor the Ferrari and Mclaren Formula One Teams.Been in the sporting focus all through the year due to the Olympics, Santander decided to see if it would be possible to stage a race in Britain's capital. They roped in Populous – the company behind the extensions made to Silverstone – into how an F1 race could be run on the city streets. The design layout suggests a start-finish straight on Mall street following on to a circuit that would race past iconic landmarks such as Buckingham Palace, Admirality Arch and Trafalgar Square.Lewis Hamilton and Jenson Button have thrown their support behind a bid for London to host a grand prix, saying it would make it the "ultimate sporting metropolis." Unveiled at the Royal Automobile Club on Pall Mall on Thursday night, the McLaren duo spoke glowingly about the hypothetical event, which would run through the streets of London. "Having been immersed in this project, having helped to shape this track, it feels as real to me as anywhere I've raced," said Hamilton. "Jenson and I worked in the simulator to provide some useful feedback to inform the circuit designers, so this is far more than whimsical thinking out loud.I have to say, this is an utterly epic track and would produce the most stunning and compelling Formula One race."Meanwhile, Bernie Ecclestone, the sport’s commercial rights holder has come forward and said he wouldn't mind financing a race if it were ever to go ahead. "If we got the okay and everything was fine, I think we could do that", he said.The circuit is currently hypothetical, though a CGI film showing how exactly it will look has been released online.
